Synopsis
High pressure will dominate weather across the northeast tonight
through Tuesday of next week. Temperatures will be slightly
below normal through the period with a slight warm up by
Tuesday. A slow moving cold front will bring a period of wet
weather for Wednesday and Thursday.

Near term through Saturday
910pm update... Continued quiet night in northern new england.

Mid and upper level cloud deck has started to thin out.

Radiational cooling getting going well. Northern locations have
already dropped into the lower to mid 50s. No significant
changes expected.

625pm update... Fairly quiet night in store for northern new
england. The forecast package is mostly in pretty good shape.

There is a bit more upper level cloudiness than previously
expected, but that looks like it should be clearing out over the
next hour or two. After that, mostly clear skies will prevail
with areas of radiational fog developing in favored locations.

Previously...

high pressure over the great lakes will build into the region
overnight. Mainly clear skies and light winds will allow for
good radiational cooling leading to some fog and low stratus to
form in valley locations towards morning. Low temperatures will
drop into the 40s across northern areas and into the low to mid
50s across the coastal plain.

Short term Saturday night
Saturday will be a nice day as the center of the surface high
crests over northern maine. Aloft there will be an upper level
low breaking off a 500 mb trough swinging through the canadian
maritimes. This will allow for cumulus clouds to form during day
Saturday with daytime heating. Winds will be out of the north
and will shift onshore Saturday afternoon with high temperatures
in 70s. Saturday night will be cool with temperatures dropping
into the mid 40s to mid 50s along with fog possible again in
valley locations.

Long term Sunday through Friday
High pressure will dominate weather across the northeast for a good
portion of the extended forecast...

high pressure situated to the east of the forecast area will produce
an onshore flow to the south of the forecast area and expect some of
this low level moisture to wrap around to the west and north
especially during the morning hours. Looking for a mix of Sun and
clouds across most of the region with a little more in the way of
clouds in the connecticut valley. Looking for fairly uniform
temperatures across the forecast area with much of the region topping
out in the lower 70s.

High pressure will build in from the northeast Sunday night
suppressing the onshore flow well south of new england. Expect
lingering clouds to gradually clear overnight allowing for good
radiational cooling. Lows temps will range from the mid 40s north to
near 50 south.

Monday will feature abundant Sun and temperatures once again in the
lower 70s for most of the region. Clear skies continue Monday night
with lows similar to Sunday night.

High pressure will produce one more nice day on Tuesday with mostly
sunny skies and slightly warmer temperatures. Highs will top out in
the lower to mid 70s.

High pressure will shift east Tuesday night as a cold front
approaches from the west. Looking for increasing clouds in western
zones after midnight and a chance of showers in the connecticut
valley toward daybreak. Lows will generally range through the
50s.

Cold front will slow on Wednesday as flow aloft becomes
parallel to the front. Looking for increasing clouds through the
day in eastern zones and mostly cloudy skies and occasional
showers in western zones. Highs will range through the 70s to
near 80.

Cold front will slowly push into the region from the west with
most of the forecast area seeing rain overnight. Lows will range
from the mid 50s to lower 60s.

Cold front will continue to make very slow eastward progress on
Thursday with rain gradually moving out of new hampshire during
the day and continuing into thurday evening in western maine.

Highs will range from the mid 70s north to the mid 80s south.

Aviation 01z Saturday through Wednesday
Short term...VFR through the weekend except for a few hours of
lifr in fog and low stratus early Saturday and Sunday mornings
at kleb and khie.

Long term...VFR Sunday through Tuesday. Areas of MVFR ceilings
developing on Wednesday.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
